# Torus Surface Area Calculator

Torus Surface Area Calculator is a web-based tool that displays the Torus Surface Area for a given input. This is a free online tool that simplifies and entertains calculations. If an input is provided, the result for the supplied number can be easily displayed.

### What is Torus Surface Area and its Formula?

A torus is a three-dimensional form made by rotating a tiny circle with radius r in space around an axis that is parallel to a larger circle of radius R. To compute the surface area of a torus, use the following formula:

Surface area of Torus = (2πR)(2πr)

Surface area of Torus **= 4 π ^{2}Rr**

The radius of the cross-section r and the radius of rotation R, which is the distance between the centre axis and the centre of cross-section are the two radii that make up a torus.

Ring type (R > r)

Horn type (R = r)

Spindle type (R less than r)

The volume of Torus is given by:

**Volume = 2π ^{2}Rr^{2}**

### What is Torus Surface Area Calculator and How to use it?

There are steps to find the torus surface area using a calculator:

- Enter the outer radius or big radius value (R)
- Put the inner radius or small radius value (r)
- Press the calculate button to get the torus surface area will be appear on the screen.

### Example on Torus Surface Area

**Question 1:** What does your average speed if the distance cover 4000 metres in 10 minutes?

**Solution:**

Consider the problem and the inputs are as such

The outer radius is 20 units

Inner radius is 10 units

The formula for finding the torus surface area is **Surface area = 4 π ^{2}Rr**

Surface area = 4 (3.14)^{2}*20*10

Surface area = 7887.68

Therefore, The surface area of a torus is **7887.68 sq.unit.**

### FAQs on Torus Surface Area Calculator

**1. What is the formula for calculating the surface area of a torus?**

The surface area of a torus is calculated by multiplying the cross-section circumference by the ring circumference. The formula for the surface area of a torus is **4π ^{2}rR**

**2. Is a torus considered a surface?**

A torus is a revolving surface created by rotating a circle in three-dimensional space around an axis that is coplanar with the circle.

**3. What exactly is a torus?**

A torus is a three-dimensional circular shape with a cross-section of a circle. Doughnuts, tyres, and basketball hoops all have this shape. When you revolve a circle along a circular path along an axis normal to the circle, you get this shape.
